These sharks are the third most auctioned on the Hongkong fin market, which represents over half of the global trade. The Silky Shark is a slender species that occurs in tropical and some warm temperate waters worldwide. First efforts to solve the evolutionary relationships of these sharks were inconclusive. If a large number of sharks are present, they remain inside the prey school. Its sense of hearing is extremely acute, allowing it to localize the low-frequency noises generated by other feeding animals, and, by extension, sources of food. They are both targeted and caught as bycatch and are often associated with fish aggregating devices (FADs). The other fins may have dusky tips. Silky sharks’ dorsal and pectoral fins appear falcate, which is sickle-shaped. Facts about the Silky shark - Carcharhinus falciformis from the Shark Research Institute (SRI).

Predators of these sharks include large sharks like Tiger sharks, great white sharks, and killer whales (Orcinus orca). Organizations such as the Inter-America Tropical Tuna and International commission for the Conservation of Atlantic Tunas have also taken steps to improve fishery monitoring, intending to reduce bycatch. Silky sharks can be found in oceanic and coastal areas in tropical waters around the globe. These sharks in most parts of the world are likely to reproduce year-round, whereas mating and birthing take place in late spring or early summer in the Gulf of Mexico (May to August). These sharks in a group have been observed to “tilt” showing their full lateral profile towards each other, also puff out their gills or gape their jaws. But they have now been classified as “near threatened” and there are some concerns about the depleting population.

The size of silky sharks pups at birth is 2 to 2.5 ft (70 – 85 cm). Based on morphology, Jack Garrick in 1982 proposed the blackspot shark (C. sealei) as their closest relative. Subsequent authors assigned this species to the genus *Carcharhinus*. The Silky Shark has a slender, streamlined body and typically grows to a length of 2.5 m (8 ft 2 in). They are both targeted and caught as bycatch and are often associated with fish aggregating devices (FADs). Young pilot fish *(Naucrates doctor)* in turn, follows these sharks while swimming against the pressure wave ahead of silky sharks. Silky sharks can swim around floating objects like tettered naval buoys or logs. In tuna fishery the Silky Shark is often bycatch. For years, scientists believed there was a very high population of this species. Leonard Compagno in 1988 assigned silky sharks phylogenetically to an informal “transitional group” also containing blacknose sharks (C.acronotus), the nervous shark (C. cautus), the blacktip reef shark (C. melanopterus), the copper shark (C.brachyurus) and the night shark (C. signatus).

Because of their abundance, they form a major component of commercial and artisanal shark fisheries in many countries. In Atlantic Ocean, they occur from the U.S. state of Massachusetts to Spain in the north and from south brazil to north Angola in the south that includes Gulf of Mexico, Meditteranean sea and Caribbean sea. The dusky shark swims in tropical and temperate oceans worldwide, cruising from depths of 1,300 feet near the continental shelf all the way in to the surf zone and other shallow inshore waters.

Occasionally, silky sharks have also been seen suddenly charging straight up, veering away just before reaching the surface and gliding back down to deeper oceans. This shark is the second most traded on the Hong Kong fin market (after the blue shark). Nevertheless, given the highly migratory nature of the silky shark and their association with tuna, there is no known simple way to reduce bycatch without affecting the economy of the fishery. This description appeared in their 1839 book titled *Systematische Beschreibung der plagiostomen*. Carcharhinus elongatus, which is an earlier representative of silk shark lineage with smooth-edged teeth is known from Oligocene deposit in the Ashley formation of South Carolina and the old church formation of Virginia.
